99.99% of scientists publishing climate papers say that human activities are causing climate change according to James L. Powell, director of the National Physical Sciences Consortium, who reviewed more than 24,000 peer-reviewed scientific articles on climate change published between 2013 and 2014.
Powell identified 69,406 authors named in the articles, four of which rejected climate change as being caused by human emissions.
That’s one in every 17,352 scientists..
“The 97 percent is wrong, period,” Powell said. “Look at it this way: If someone says that 97 percent of publishing climate scientists accept anthropogenic [human-caused] global warming, your natural inference is that 3 percent reject it. But I found only 0.006 percent who reject it. That is a difference of 500 times.”
To obtain his figures, Powell—a member of the National Science Board under Presidents Ronald Reagan and George H.W. Bush—reviewed the abstracts of nearly 70,000 papers, searching for key words such as “global warming,” “global climate change,” and “climate change.” He spent nine months reading titles and abstracts, finding only five articles (two from the same author) that clearly reject human-caused global warming or give another explanation for the rising temperatures.
